The action of lifting an arm can seem like a thoughtless movement‚ however‚ there is complex and intricate process that goes on within the human body to make that small movement happen. It involves bones‚ muscles‚ and nerves to complete this process‚ but it would not be able to start without a certain subconscious thought beforehand. Lateral abduction of the arm is defined as raising the humerus‚ radius‚ and ulna bones to ninety degrees‚ parallel to the ground‚ with the elbow extended‚ and wrist

Nervous System Differences according to: Motor neurons Sensory neurons Autonomic neurons Function Transmits impulses from the CNS which consists of the brain and spinal cord to muscles and glands elsewhere in the body Transmits impulses inwards from the sense organs to the CNS Located within the CNS‚ they transmit the electrical impulses generated by the stimuli to other nerves Structure Have Dendrites‚ Cell Body‚ Myelin Sheath‚ Node of Ranvier and Synaptic Knobs. The cell body is

Ependymal cells engulf and destroy microbes and cellular debris in inflamed or degenerating brain tissue. 5. Oligodendrocytes form myelin sheaths around nerve fibers in the CNS. 6. Nerve fibers with many Schwann cells forming a thick myelin sheath are called myelinated fibers‚ or gray fibers. 8. Most

Homeostasis Homeostasis Is a technical term for the process of maintain a constant internal environment despite external changes. The internal environment‚ compromises; blood‚ tissue fluid‚ body cell contents and all the metabolic processes taking place. Constant in this instance is not absolute or fixed it is much more flexible and dynamic as it refers to the physical and chemical composition being kept within a limited range or variables for maximum efficiency‚ well-being of the whole body and
